pub type MarkdownBlockParserFn = dyn for<'a> Fn(&Node, &MarkdownParseContext<'a>) -> Option<MarkdownNode> + Send + Sync;Expand description
Type for a custom Markdown block parser.
Parsers run during Markdown AST conversion, often on a background task. They
must not depend on Window or App; return parsed, reusable data in a
MarkdownNode and render it later with a block renderer.
